Correct Answer: 68. (4)
Solution: 68. (4) I. Saving
$=100 %-(25+45) %=30 %$
Since Salary is not known,
[By Approximation] savings can’t be calculated.
I & II $25 %=₹ 15000$
$\therefore$ Savings $=30 %$
$=15000 \times \frac{30}{25}=₹ 18000$
I & III. Similar to I & II
II & III $45 %=27000$
$\therefore \quad$ Salary $=100 %$
$=27000 \times \frac{100}{45}=₹ 60,000$
Savings
$=60000-(15000+27000)$
$=₹ 18000$
So, any two of the three are sufficient to determine the answer.
